Fun with groups

The Cayley table for the beloved quaternion group

  1 -1 i -i j -j k -k
1 1 -1 i -i j -j k -k
-1 -1 1 -i i -j j -k k
i i -i 1 -1 k -k j -j
-i -i i -1 1 -k k -j j
j j -j k -k 1 -1 i -i
-j -j j -k k -1 1 -i i
k k -k j -j i -i 1 -1
-k -k k -j j -i i -1 1

Here it is again without the legend row and column and just the colors. Enjoy the symmetry!
